Bu çalışma, bıldırcın rasyonlarına öğütülmüş rezene tohumu ilavesinin bazı kan parametreleri ve karaciğer oksidan-antioksidan parametreleri üzerine etkilerini belirlemek amacıyla yapılmıştır. Çalışmada 32 adet (16 adet erkek+16 adet dişi) japon bıldırcını kullanıldı. Her bir grupta 8 hayvan olacak şekilde, katkı içermeyen bazal yemle beslenen kontrol erkek, kontrol dişi ve bazal yeme %1 öğütülmüş rezene tohumu ilavesi ile beslenen rezene erkek, rezene dişi olmak üzere dört grup oluşturuldu ve 28 gün beslendi. Rasyona % 1 öğütülmüş rezene tohumu ilavesinin, karaciğer MDA düzeyini ve GPx aktivitesini azalttığı ve Vit C düzeylerini ise arttırdığı (P0.05). Çalışma, bıldırcın rasyonlarına % 1 öğütülmüş rezene tohumu ilavesinin serum total kolesterol, LDL, HDL düzeyleri, AST ve ALT aktivitelerini değiştirmeksizin, karaciğer oksidan-antioksidan dengeyi etkileyebileceğini göstermiştir. Ayrıca bıldırcınlarda serum ve karaciğer değerlerinin cinsiyete bağlı olarak farklı olabileceği de bu tarz çalışmalarda göz önüne alınmalıdır.

WOS: 000378892800003, This study was carried out to investigate the effects of eggshell colour and spot properties (colour and size of the spot area) on eggshell incubation temperature and hatching outcomes of Japanese quail eggs (Coturnix coturnix japonica). Study material was allocated to five groups according to their eggshell and spot colours: black spots on greyish white coloured eggshell (I), blue spots on greyish white coloured eggshell (II), diffuse brown spots on greyish brown coloured eggshell (III), brown spots on light green coloured eggshell (IV), and small brown spots on greyish brown coloured eggshell (V). The size of the spotted area was determined in each egg group using digital image analysis. Mean relative weight losses of hatched and unhatched eggs between days 0-10 and 0-14 of embryonic development were 4.76% and 10.48% and 9.17% and 15.46%, respectively. The mean eggshell temperatures of hatched and unhatched eggs measured at the equatorial region on days 10 and 14 during embryonic development were 36.92 and 37.79 degrees C and 36.84 and 37.18 degrees C, respectively. Eggshell temperatures at the equatorial region on days 10 (36.89 degrees C) and 14 (37.57 degrees C) of embryonic development were lower than the fixed temperature of the incubator (37.6 degrees C). Fertility, hatchability of fertile eggs, and hatchability and embryonic mortality rates do not vary in relation to eggshell colour or the size of the spotted area., Scientific Research Project Unit of Mustafa Kemal University, Turkey [1206 M0117], This study was conducted between February and April, 2013. Present study was supported by the Scientific Research Project Unit of Mustafa Kemal University, Turkey (Project number: 1206 M0117).

WOS: 000385454300002, This study was carried out to investigate the effects of eggshell colour and spot properties (colour and size of the spot area) on growth performance and carcass traits of Japanese quail (Coturnix coturnix japonica) eggs. Study material were allocated to five groups according to their eggshell and spot colours: black spots on greyish white coloured eggshell (I), blue spots on greyish white coloured eggshell (II), diffuse brown spots on greyish brown coloured eggshell (III), brown spots on light green colored eggshell (IV), and small brown spots on greyish brown coloured eggshell (V). The size of the spotted area was determined in each egg group using digital image analysis. The groups did not differ for body weight and length of the shank at the end of the growth period. However, the groups differed significantly for carcass yield after slaughter (not eviscerated) and carcass yield. These parameters were highest in Group I (82.08 and 76.09%) and lowest in Group III (80.20 and 73.86%). Digital image analysis demonstrated that heart length, cardiac fat area, gizzard width, and intestine length varied between the groups. Cardiac fat area was largest in Group III (0.86 cm(2)) and smallest in Group V (0.65 cm(2)). Gizzard width was greatest in Group I (2.63 cm) and smallest in Group V (2.47 cm). Intestine length was greatest in Group V (78.45 cm) and smallest in Group IV (72.39 cm). Body weight, shank length, and slaughter and carcass weight do not vary in relation to eggshell colour or the size of the spotted area. The lengths of intestine and heart, gizzard width, and cardiac fat area do vary in relation to eggshell colour or the size of the spotted area., Scientific Research Project Unit of Mustafa Kemal University, Turkey [1206 M 0117], The present study was supported by the Scientific Research Project Unit of Mustafa Kemal University, Turkey (Project no. 1206 M 0117).

WOS: 000365036300001, This study was carried out to evaluate the use of propolis extract on egg storage time of table quail (Coturnix coturnix Japonica) eggs. Propolis is a sticky, resinous, dark-colored material that honey bees collect from young plants. In the experiment, 600 quail eggs were used and eggs were coated with various concentrations of propolis extract (0%: group I, 5%: group II, 10%: group III, 15%: group IV) and treated with 70% ethyl alcohol (group V). A 5-week storage period was implemented, and 120 eggs were used for each group. Consequently, the effects of storage time and shell treatments on storage time and the effects of treatments on the interior quality of eggs were determined. The results of the study confirmed highly significant differences between weekly changes in egg weight loss, albumen-yellow indexes, and Haugh units (P < 0.001). While the difference in yolk index between groups was insignificant, the difference between groups with respect to albumen index (P < 0.001), Haugh units (P < 0.001) albumen pH (P < 0.001), and egg weight loss (P < 0.001) were significant. The significance of the overall difference with regard to Haugh units varied among groups; for example, group IV showed the highest value of 87.73%, followed by group III (87.69%), group II (86.97%), group V (85.53%), and group I (85.21%). Albumen pH levels were increased with increasing storage time for each treatment group. The best egg protection results in terms of interior quality were obtained in eggs coated with 10% and 15% propolis extract during storage., Scientific Research Project Unit of Mustafa Kemal University, Turkey [1201M0110], This study was supported by the Scientific Research Project Unit of Mustafa Kemal University, Turkey (Project number: 1201M0110).
